On Thursday, pictures of [artist id="3079280"]Demi Lovato[/artist] circulated the Web showing the actress/singer at [article id="1596353"]Miley Cyrus' Sweet 16 party[/article] in October with strange marks on her wrists. The marks led Perez Hilton to make serious accusations that perhaps the 16-year-old "Camp Rock" star had inflicted the wounds on herself, implying that she is prone to self-mutilation.

In a statement to E! News, the singer's rep denied Hilton's claim. "Demi was wearing gummy bracelets just prior to her appearance on the red carpet and, because of how tight they were, they left indentations on her wrist," publicist Allison Leslie said.

"These allegations are completely false," her other rep, Lillian Matulic, told the New York Daily News. Perez Hilton later posted the reps' statements on his Web site.

The busy teen star — who has admitted to being a [article id="1593780"]closet metalhead[/article] — burst on the scene earlier this year when she starred in the Disney Channel movie "Camp Rock," alongside the [artist id="2088128"]Jonas Brothers[/artist]. Her first album, Don't Forget, which the Jonas Brothers helped write, debuted at #2 earlier this fall. Lovato is currently working on her new Disney TV series [article id="1596461"]"Sonny With a Chance,"[/article] slated to premiere early next year.

"I play Sonny, who's a girl from Wisconsin, and she kinda sticks out like a sore thumb, 'cause she's very quirky and very over the top," Lovato cheerily told MTV News in October. "She comes to L.A. to be on her favorite TV show. It's like '30 Rock,' but for the Disney Channel."
